METAL UNDERFBAMIING FOR CARS.

eeaesa.

To all whom it my concern:

- ing for Cars, of which the following is a specification, and which are illustrated in t e accompanying drawings, forming a part thereof.

The invention relates to improvements in metal under-framin for cars and is of that type in which the ibad is transmitted to a palr of longitudinal sills arranged adjacent the median line of the car, these sills carrying frame-work projecting outwardly to and carrvin the side sills.

The 0 jectsof the invention. are to provide a. simple form of construction yet one having great strength in that the bolts or rivets, by means of which the parts are secured together, are largely. relieved from carrying stresses; the invention consisting in a structure as is hereinafter deseribedand is illustrated the accompanying drawings, in which-- Figure 1 is a detail lan view of the under framing of the car; l ig. 2 is a detail sectional view on the line 22 of Fig. 1., i ig;

3 is a detail sectional view on the line 3-3 of Fig. 2; Fig. 4 is a detail of-the underframing in perspective, showing a portion of the body bolster; and Fig. 5 is a detail in perspective, showing the juncture of one of the center sills with a bolster and an angle brace. T

The main or center sills are shown at 10, 11, and are in the form of I-beams and extend from end to end of the car, being located adjacent to and one upon eadi side of the median line of the car. The cross sills are in the form of angle bars, as shown at 12, and project throiwh suitable openings, as 13, in the webs of the sills 10, 11, one flange 14, of the cross sill, being horizontal, the other flange 15 projecting downwardly therefrom. The side sills 16 are also in the form of angle bars, resting upon the cross sills at their outer ends, the angle being outwardly directed, and a nailing strip 17- being seated within this angle and securely bolted to the sill. A filling and supporting bracket 18, preferably a malleable casting, is sealed against the outer face of the web of the center sill and upon its outer foot flange and engages and supports the cross .sill from the Specification of Letters Patent.

center sill to its outer end, the upper edge of this bracket bearing against the horizontal flange of the cross sill and lying against and being riveted to the vertical flange 15.

At the inner end of the bracket there is a flange 19, through which rivets are passed to secure it to the web of the center sill, and at its lower edge the bracket is provided with a lateral strengthening llangc 20. The above specific construction of the cross sill applies to the sills intermediate of the body bolsters. These bolsterscomprisc a pair of such sills difi'ering, however, from the in mediate sills in that the bottom flanges 2?; of the bracket members project in opposite di-' rections or toward the median line of the bolstei. These holsters,{urther 'comprisu filler platesflil located between the rumor sills and confi-irniing to the contour then of, one olf suclnplates being associated with each of the cross sills forming a part oi the bolster and being riveted to the pendent flanges thereof, as shown at 24. Each of these filler plates having lateral flanges 25, which give added strength and allord means of attachment to the webs of the longitudinal sills by means of rivets, are shown at 26. A tie plate 27 is applied to the under face of the bolster and is riveted to the lateral flange of the supporting brackets and to the flanges 25 of the filler plates .33. The usual floor-carrying strips 28 are applied to the upper faces of the cross sills, and to these the lien" 29 of the car is nailed.

The brackets 18 constitute chairs upon which the outer ends of the cross sills are seated and through which-the load is trunk mitted to the center sills, the rivets attaching these brackets to the cross sills being located below the upper flanges oi the latter, are largely relieved lro1n "tli(, showing stresses incident to thc' tendcni-y ofthvse sills to bend downwardly.

I claim as lily-invention 1. In metal under-fran|ing for cars, in combination, a longitudinal sill having an outstandin bottom flange, an angle bar perpendicu ar to and extending through the sill, its flanges being horizontally and wartically disposed, and a plate titling within the angle of the sill and hearing against the under face of the horizontal iiange oi the angle bar and being secured to the vertii-al. flange thereof.

2. In metal under-framing for cars, in

combination 1 longitudina sill uts1anhug bottom liaugex an p rpemlicnlar in the sill and through the web thereof, one of aving an angle bar ex ending its flanges being horizontal unit the other zlepemling therefrom. and a plate fitting Within the angle of the sill and healing agains the under face of the h riz ntal flange. of the angle bar and being secured to the ielnlent flange thereof.

3. In metal uruler-framing for cars. in

combination, a pair at longitudinal ills adacent the median line of the car, each Slit the center sills and being seated against the I V web and root flange thereof, the upper ed'res I of such brackets bearing against the lower nose-9e face of Lhe horizonta llange of the angle bar and the side face of the pendent flange thereof and being secured thereto by means of rivets, and a tiller interposed between the :enter sills.

4. In metal under-framing combination, a pair of center form of I-beams, a plurality of passing through the Webs of the 0f sueh bars having zont-al and the other pendent, apair of supportin brackets being seated against the outer aces of the webs and bottom flanges of the sills and engagin' the horizontal flange of the angle bar an being riveted to the vertical flange thereof.
